Here I have written a rough draft for my first SCP concept. The idea itself is not original, the SCP story is. I can add more details down the road. I'm open to feedback, and if you must throw this down a drain, I understand.

Our first Kronecker!?
No, not really, as it's O5 that's keeping the information under protection.
I don't think there's anything called data corruption, and Expunging all anomalous data sounds like you couldn't come up with anything.
Basically, you should say the properties instead of hiding them.
-My opinion.

Also from what I can read it sounds like another thing that's gonna destroy the world in X amount of time. I personally dislike those.

Basically it get rid of the anomalous data little by little so that the workers are convinced it isn't special. This isn't actually a Kronecker, but there's very little anomaly here so I was reminded of the SCP.

I feel like you know what you have to change here so far on these terms. The community did a good job of clearing up my opinion.

Since Kronecker is still a new thing, I highly recommend that you contact the author of 2062, InsipidParoxysm, before drafting this idea up. It's the polite thing to do, and they'll be able to help you make sure you're writing their idea up right (remember to ask nicely!)

I'm not really seeing what's anomalous about this. It's a planet that could send comets our way, so it's dangerous, but that doesn't mean the Foundation needs to get involved. It seems like they could have left it to NASA.

You did mention that it's only visible in infrared. I'm not an expert, so I can't say how unusual that is. In any case, though, that detail didn't really get used elsewhere. Why is it only visible in infrared? Does that have any interesting consequences?

For the record, it's extremely unusual. Hell, it's actively impossible, and would make the planet anomalous.

For my own thoughts… This might have cut the mustard in series I, but probably not anymore. I'm a sucker for space stuff, and even I don't think there's enough to this scip. It needs more meat to it, maybe additional affects, or a log of some kind, or something.

Also, there's no reason for the data corruptions. Expunge them, or actually don't because expungement is normally an awful idea.

Expungement doesn't necessarily mean that the article within is going to suck; there are many modern-day SCP's that use this to great effect. What matters is that the expungement in question is not used as a "Well, I couldn't think of anything, so have an expungement" mechanism.

I took the effects away and expunged them for effect. I understand that I might've taken away too much, so I can place them back in. I can add more to it, such as why the O5 wants it secret. Or maybe what the O5 assigned Dr. Lebeau to. I'll take away the doomsday, but I'll leave the chance that it can cause a End of the World scenario.

Right off the bat, the pre-revision paragraph is not particularly anomalous. Weird physics (being opaque to visible light and up), sure, but not really anomalous. I know it's supposed to be redacted, but the Foundation makes up information in those cases.

The O-5 conversation feels very tacked-on where it stands.

Otherwise, this is a not very interesting retake on The Hateful Star's concept. Technically it's more dangerous, but in the end it's just an impending alien attack.
